Ive recently upgraded my PC and my nwn has stopped working,It goes as far as the main menu but then the screen dies but the game keeps running,.Ive upgraded to a quadcore processor and a gigabyte ga-73pvm-sh2 board with 2GB of ram anyone got any ideas on whats up?

1.) Maybe your settings in your nwnconfig.ini settings are still pointing to your old specs? Check it out (If default C:\NeverwinterNights\NWN\nwnconfig.ini ) There is also the nwnconfig.exe utility. You may want to try it and select "change" when it opens up and go through that prompt.
